What could cause heavy or difficult steering in your vehicle?

Heavy or difficult steering in a vehicle can often be attributed to under-inflated tyres. When tyres are under-inflated, they do not maintain the proper contact with the road surface, which can lead to increased rolling resistance. This means that the steering system has to work harder to turn the wheels, resulting in a heavier feel in the steering wheel. Not only does this affect maneuverability, but it can also lead to uneven tyre wear and reduced fuel efficiency. Maintaining the correct tyre pressure is crucial for ensuring optimal handling and safety while driving.

In contrast, over-inflated tyres can cause a different set of issues, such as a harsher ride and less grip, but they typically do not lead to heavier steering. Worn brake pads primarily affect braking performance rather than steering response, and a faulty steering mechanism would directly cause steering difficulties but is a specific issue unrelated to tyre inflation levels.
